Abstract
A control unit of a radiation imaging apparatus includes: an exposure time control unit which controls a subframe exposure time of an image sensor such that focused fluorescence at a depth of field generated by radiation reaching a scintillator and out-of-focus fluorescence deviating from the depth of field are discretely imaged on a light receiving surface of the image sensor for each particle of the radiation; a focused signal discrimination unit which discriminates between sensor signals of a light receiving pixel group corresponding to spots of the focused fluorescence discretely included in each subframe and sensor signals of a light receiving pixel group corresponding to spots of the out-of-focus fluorescence; and an image signal processing unit which generates an image by overlaying subframe data based on the sensor signals from the light receiving pixel group corresponding to the spots of the focused fluorescence.
